Last updated: April 2026 dataChloroprene rubber latex — the aqueous dispersion form of CR, also known commercially as neoprene latex — is a specialty elastomer input used in adhesives, coatings, dipped goods, and flame-retardant applications. Germany leads US import supply, followed by Japan and Switzerland, reflecting the concentration of CR latex production among a small number of global chemical manufacturers. The single US tariff line covering this product is 4002410000. Importers should verify country-of-origin documentation carefully given the multi-country processing chains common in specialty chemical supply.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The latex (aqueous dispersion) form falls under HTS 4002410000, while solid or primary-form chloroprene rubber — including plates, sheets, and strip — is classified separately under 4002490000. The physical state at time of importation determines which line applies.
A certificate of origin or manufacturer's declaration is standard, along with a commercial invoice identifying the specific polymer grade and CAS number. Because CR latex is a chemical intermediate, some buyers also request a safety data sheet and technical data sheet to confirm product specification and support end-use classification decisions.
